PATRICK HENRY, OF BRADFORD, ENGLAND.

DABBING-BRUSH.

Specification of Letters Patent.

Patented May 26, 1908.

Application filed January 7, 1908. Serial No. 409,629.

To all whom it may concern:

Beit known that l, PATRICK HENRY, a subject of the King of Great Britain, residing at Bradford, in the county of York, England, have invented certain new and useful 1mprovements in a Dabbing-Brush, of which the following is a specification.

This invention relates to certain new and useful improvements on my dabbing brush for which patent was granted to me in Great Britain, August 30, 1905, No. 14246, the object being to improve the construction of the back plate, and provide very novel means for securing it to the stock, whereby it will be held very rigid thereonand can be easily and quickly taken off-when desired.

Another object of my invention is, to improve the construction of plugs used for adjusting the bristles in the bores of the stock, whereby the binding action of the drawing wire caused by the plug forcing the wire against the head of the bores will be prevented, so that the wire will havefree movement through the same, thereby drawing'the bristles tighter within the bores, than accomplished in my former patent.

These objects are obtained by the novel arrangement and construction of parts hereinafter fully described and shown in the accompanying drawings, in which:

Figure 1, is a perspective view of my improved brush partly broken away to show the manner of securing the heads of the fastening bolts for the back plate. Fig. 2, is an inverted top plan view of the back plate. Fig. 3, is a detail sectional view of the stock, showing the manner of adjusting the bristles in the bores, and, Fig. 4, is a perspective view of one ofthe plugs detached.

Referring to the drawing, A indicates a wooden stock provided with oppositely disposed enlarged portions A and an outwardly projecting tongue A2, the enlarged portions and tongue being provided with vertical bores, which communicate with square recesses formed in their lower faces, for the purpose hereinafter fully described. The underside of the stock is provided with a plurality of vertical bores B which communicate with openings C formed in the top of the stock, and through which the drawing lwires D are adapted to pass for securing the bristles E therein.

The bristles E are provided with heads E through which the drawing wires D are adapted to pass. The heads being formed by gluing a number of hairs together and binding the same by any suitable means. Vhen the bristles become worn and it is desired to force the same further out of the bores, wooden plugs F of any desired length having vertical bores F are placed in the bores of the stock, the bores F communicating with the openings C of the stock A. lt of course being understood, that the drawing wire D has been previouslycut so as to allow the bristles to be removed, when it is desired to secure the bristles in the stock. The drawing wire is forced vdownwardly through one of the openings in the top of the stock, through the bore of the plug, and transversely through the head of the bristles and then brought back again and then over to the adjacent opening of the stock, the same operation being repeated, the latter being the ordinary manner of securing the bristles in a stock by a wire.

It will be seen that by passing the drawing wires through the bore of the plug instead of around the same, as was done in my former patent, the plugs will not bind the drawing wires against the head of the bore when drawn on, thereby enabling the bristles to be drawn much tighter within the bore and securely held therein, so that it will be impossible for the same to move in any direction.

Arranged on the stock A is a plate G substantially the same shapeas the stock, having oppositely disposed aperture ears G, and an outwardly projecting aperture tongue G2, the apertures of the ears and tongue registering with the vertical bores formed in the enlargements and the tongue of the stock, through which bolts H are adapted to pass, which are provided with square heads H, fitting in the square recesses formed in the enlargements and tongue. The plate being securely locked thereon by nuts H2 working on the bolts H which will bind the plate securely in the top of the stock and prevent the same from wabbling or moving in any way. lt will be seen that by this arrangement the plate can be removed much easier and quicker than with the arrangement l used in my former patent, and at the same time will be held thereon very rigid.

Recesses G3 are formed in the enlarged portions formed on the underside of the plate, which communicate with square openings G4 extending through the plate in which the heads of bolts I are adapted to nt. The Shanks of the bolts being provided with square portions I fitting within the square opening G4, so as to prevent thebolts `from turning, these bolts are for the purpose of securing the brush to the actuating machine, and it will be seen that these bolts are so se-Y cured within the back plate that they will not work loose, and will be held rigidly thereon at all times.

Freni the foregoing description it will be seen that I have greatly improved the con? struction of my dabbing brush patented in Great Britain, without increasing the cost of manufacturing the same to any great extent.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A brush comprising a stock provided with a plurality of bores to receive bristles, adjusting plugs provided with longitudinal bores adapted to be arranged within said bores, and drawing wires adapted to pass through the stock, plugs and bristles for the purpose set forth.

2. A brush comprising a stock provided with a plurality of bores in its underside, communicating with openings of a smaller diameter'formed in the top of the brush, plugs provided with longitudinal bores arranged in the bores of the stock, bristles arranged in the bores and drawing wires passing through the openings of the stock, bores of the plugs and heads of the bristles, for the purpose set forth.

3. A brush comprising a stock provided with oppositely disposed enlargements and an outwardly projecting tongue, said enlargements and tongue being provided with vertical bores communicating with square recesses formed in their undersides, a back plate substantially the same shape as the stock, arranged on the upper side of the` stock having oppositely disposed aperture ears, and an outwardly projecting tongue, the apertures of said ears and tongue regis.- tering with the apertures of the enlargements and tongue ofthe stock, bolts extending up wardly through saidbores of the stock and through the aperture ears and tongue of the back plate, said bolts being provided 'with square heads fitting in the recessesformed in the enlargements and tongue of the stock, nuts working on said bolts for clamping said plate thereon, said plate being provided with square openings, and bolts provided with square portions on their shanks extending up through the square openings formed in said back plate for securing said brush to the actuating machine.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

PATRICK HENRY.
